MATERIALS AND PROCEDURES: Forty missing teeth were replaced with implants in matched subjects. Parameters assessed were "distance of cement enamel junction to alveolar crest and distance of CEJ to gingival margin; bleeding on probing, Sulcus probing depth, and peri-implant marginal bone loss." Subjects were randomly assigned for the two groups of intervention. All the measurements were documented at designated timelines and compared for the statistical variance where P < 0.05 was considered as significant.
RESULTS: In the control and test groups, the peri-implant marginal bone level rose from baseline to 3 months. There were no appreciable differences between the CEJ-AC and CEJ-GM groups when the clinical and radiographic parameters of each group were evaluated. Throughout all of the time points, the soft tissue borders in both groups remained comparably steady.
CONCLUSION: The study's findings suggest that using implants with definite abutments is more advantageous for obtaining better maintenance in terms of the health of the tissues that surround the implants.
MATERIAL AND METHODS: For the current in vitro study, 60 volunteers donated each 10 ml of their blood and hence a total volume of 600 ml of blood was procured that was analyzed for the current study. The total volume was grouped to three groups where they receive three resistance centrifugation forces of "F-200,600,800 m/s²." In each group, 20 samples were tested for each level of the G-resistance. Each group was further divided as two subgroups of different times of wait, where they were centrifuged at baseline time and after a stand of 30 minutes. On universal testing equipment, the PRF membranes were mechanically tensioned in order to determine each membrane's resistance force. These values were compared for any statistical variance using appropriate statistical tools keeping P < 0.05.
RESULTS: Any applied force had no statistically significant effect on the centrifugation duration for membrane resistance. When the resistance was applied for the PRP samples immediately after they were procured, no significant variation was seen at all the grades of the centrifugation forces; consequently, the T30 group showed a statistically significant variance for the centrifugation forces applied (P = 0.04), with the highest value when the greatest force was applied. According to the results, the centrifugation waiting period could be determined based on the application requirement.
CONCLUSION: For immediate membrane usage, the centrifugation had no effect on resistance; however, after 30 minutes, a membrane with greater resistance was produced by applying more force.
MATERIALS AND METHODS: Test medias used in this study included carbonated beverage, noncarbonated beverage, high-energy sports drink medicated cough syrup, distilled water as the control. A total of 110 previously extracted human premolar teeth were selected for the study. Teeth were randomly divided into two groups. Test specimens were randomly distributed to five beverages groups and comprised 12 specimens per group. Surface roughness (profilometer) readings were performed at baseline and again, following immersion for 14 days (24 h/day). Microleakage was evaluated. The results obtained were analyzed for statistical significance using SPSS-PC package using the multiple factor ANOVA at a significance level of P < 0.05. Paired t-test, Friedman test ranks, and Wilcoxon signed ranks test.
RESULTS: For surface roughness high-energy sports drink and noncarbonated beverage showed the highly significant difference with P values of 0.000 and 0.000, respectively compared to other test media. For microleakage high-energy sports drink had significant difference in comparison to noncarbonated beverage (P = 0.002), medicated syrup (P = 0.000), and distilled water (P = 0.000).
CONCLUSION: High-energy sports drink showed highest surface roughness value and microleakage score among all test media and thus greater erosive potential to enamel while medicated syrup showed least surface roughness value and microleakage among all test media.
Aim and Objectives: The aim of this study was to evaluate the flexural strength of a high-impact PMMA denture base resin material and flexural strength of a commonly available heat cure PMMA denture base material with Kevlar, glass, and nylon fibers.
Materials and Methods: The test samples were studied under two groups. The Group I (control group) comprised pre-reinforced PMMA (Lucitone 199; Dentsply Sirona Prosthetics, York, Pennsylvania, USA) consisting of 12 samples and second group comprised regular PMMA (DPI, Mumbai, India) reinforced with different fibers. The second test group was further divided into three subgroups as Group 2, Group 3, and Group 4 comprising 12 samples each designated by the letters a-l. All the samples were marked on both ends. A total of 48 samples were tested. Results were analyzed and any P value ≤0.05 was considered as statistically significant (t test).
Results: All the 48 specimens were subjected to a 3-point bending test on a universal testing machine (MultiTest 10-i, Sterling, VA, USA) at a cross-head rate of 2 mm/min. A load was applied on each specimen by a centrally located rod until fracture occurred; span length taken was 50 mm. Flexural strength was then calculated.
Conclusion: Reinforcement of conventional denture base resin with nylon and glass fibers showed statistical significance in the flexural strength values when compared to unreinforced high impact of denture base resin.
Materials and Methods: This school-based study was conducted on 520 children of age group of 12-14 years of both genders. Location, education, and employment status of parents, use of toothbrush, frequency of brushing, dental floss, total number of meals in a day, number of snacks between meals and sugar consumption, and decayed, missing, filled teeth were recorded.
Results: There were 266 males and 254 females. Age group 12 years had 80 males and 90 females, 13 years had 70 males and 60 females, and 14 years had 116 males and 104 females. Ninety-six males and 110 females were from urban and 170 males and 144 females were from rural. The mean plaque score in 12-year male children was 0.61 ± 0.32, in 13-year children was 0.68 ± 0.45, and in 14 years was 0.74 ± 0.48. In males, the mean plaque score was 0.70 ± 0.38 and in females was 0.66 ± 0.42. In children from urban area, the mean plaque score was 0.62 ± 0.34 and from rural area was 0.74 ± 0.40. Four hundred and eighteen children were using toothpaste and they had plaque score of 0.76 and 102 children were using floss and they had plaque score of 0.89. Three hundred and twenty children were brushing once, 90 twice, and 110 irregular and there mean plaque score was 0.70, 0.61, and 0.76, respectively. The difference was significant (P < 0.05).
Conclusion: Authors found that oral health status of children consuming high sugar, more snacks per day, and brushing occasionally was poor.
Materials and Methods: Institutional ethical clearance was obtained. A total of 206 patients who reported to the Department of Hematology for blood investigations were the participants in this study. Age, sex, place, weight, height, dental fluorosis, and skeletal complaints were noted down. Body mass index was calculated, and statistical analysis was performed.
Results: Dental fluorosis was present in 63.1% and absent in 36.9% of the samples reported. Skeletal fluorosis was present in 24.8% and was absent in 75.2%. A large number of the patients had knee pain and difficulty in bending. Chi-square test was used for statistical analysis. Skeletal fluorosis and age were compared and P value was 0.00 and was significant. Dental fluorosis and skeletal fluorosis were compared and P value was found to be 0.000 and significant.
Discussion and Conclusion: There is a need to take measures to prevent dental and skeletal fluorosis among the residents of Salem district. Calcium balance should be maintained, and fluoride intake should be minimized to reduce the symptoms. The government should provide water with low fluoride level for drinking and cooking. Once the symptoms develop, treatment largely remains symptomatic, using analgesics and physiotherapy.
Materials and Methods: The questionnaire was first translated into the Malay language (RDAS-M). In this cross-sectional study, healthy married Malay women in Kota Bharu, Kelantan, were recruited from January to April 2018. Participants were asked to complete the RDAS-M that consists of three domains, that is, dyadic consensus, dyadic satisfaction, and dyadic cohesion with a total of 14 items. The concept, content, and construct validity using exploratory factor analysis (EFA) and reliability of the RDAS-M were assessed.
Results: Of the 164 recruited participants, 150 consented to participate. The mean age of the participants was 34.1 years (standard deviation [SD], 9.5 years), ranging from 20 to 57 years. All 14 items were considered comprehensible by more than 95% of the subjects. Based on EFA, total variance extracted was 69.08%, and the original three factors were retained. The Malay version of the RDAS was valid based on factor loadings for dyadic consensus, dyadic satisfaction, and dyadic cohesion, which ranged from 0.64 to 0.80, 0.79 to 0.98, and 0.37 to 0.78, respectively. The internal consistency was good with coefficient α of 0.87 for dyadic consensus, 0.93 for dyadic satisfaction, and 0.78 for dyadic cohesion.
Conclusions: The Malay version of the RDAS is easy to understand, and is a reliable and valid instrument for married women. It is also comparable with the original version of the RDAS in terms of structure and psychometric properties.
Data Sources and Methods: A retrospective study based on telephone calls reported on poisoning caused by pharmaceutical products undertaken by the National Poisoning Centre (NPC) in Penang (Malaysia) was used as the basis of this study covering the period between 2010 and 2015. The study included the mode and type of poisoning, exposure routes as well as the incidence locations.
Results: A total of 10,998 cases were examined, finding that females represented 5,899 cases (53.6%) being intoxicated more frequently compared to the number of males, 3,839 (34.9%). The age group of poisoning cases ranged between 20 and 29 years representing 2,579 (23.4%) of reported cases. The common mode of poisoning was attributed to suicide 5,203 (47.3%) from among the 10,998 cases and the highest poisoning agents reported were from the psychiatric group of pharmaceutical products of 2,287 (21%).
Conclusion and Implications: These findings indicate a rising trend of suicidal poisoning attempts between 2013 and 2015, which emphasizes the need for more stringent and effective enforcement protocols to limit the rising incidence of poisoning. As such, analyzing the trends in poisoning in a particular zone periodically could help health policy-makers to develop management policies and prevention strategies.
Objective: This study addressed the therapeutic effect of 3-(2,5-dimethoxyphenyl)-1-(5-methyl furan-2-yl) prop-2-en-1-one (DMPF-1); synthetic chalcone derivative, on antinociceptive activity in vivo.
Materials and Methods: The antinociceptive profile was evaluated using acetic-acid-induced abdominal writhing, hot plate, and formalin-induced paw licking test. Capsaicin, phorbol 12-myristate 12 acetate (PMA), and glutamate-induced paw licking test were carried out to evaluate their potential effects toward different targets.
Results: It was shown that the doses of 0.1, 0.5, 1, and 5 mg/kg of DMPF-1 given via intraperitoneal injection showed significant reduction in writhing responses and increased the latency time in hot-plate test where reduced time spent on licking the injected paw in formalin and dose contingency inhibition was observed. The similar results were observed in capsaicin, PMA, and glutamate-induced paw licking test. In addition, the challenge with nonselective opioid receptor antagonist (naloxone) aimed to evaluate the involvement of the opioidergic system, which showed no reversion in analgesic profile in formalin and hot-plate test.
Conclusion: Collectively, this study showed that DMPF-1 markedly inhibits both peripheral and central nociception through the mechanism involving an interaction with vanilloid and glutamatergic system regardless of the activation of the opioidergic system.
